Perhaps you should try some spelling variations:
communication function » communication functions, communication foundation, communicative functions
based dispersion » wave dispersion, gas dispersion, based discussion
array arcing » array forming, array probing, array sharing
array range » ray range
arrays a » arrays _

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "communication function based dispersion ((((array arcing) OR (array range))) OR (arrays a))~".
• Adding a wildcard symbol may retrieve word variants: communication function based dispersion ((((array arcing) OR (array range))) OR (arrays a))*.
